Atmosphere starts becoming thin right at 5 kms (5000 metres) above sea level. High altitude trekkers would know how it becomes difficult to breath once you cross 12000 ft. Remember, at top of mount Everest, (8848 Metres) air is very thin and many climbers take oxygen with them. From 10000 metres onwards, it becomes extremely cold and rarefied. Have you heard pilot briefing you during a flight that outside temperature (at roughly 11000 metres) IS AROUND -35% c?

Zero, the atmosphere starts at the top of the ground.
